Using big data approaches to develop cell therapies – Drug Target Review

An area where stem cell biology and medicine are combining effectively is the establishment of new cell therapies. However, current therapies are limited to a narrow set of cell types that can be isolated or created and expanded in vitro. Dr Owen Rackham discusses how utilising computational approaches will further enhance applications of stem-cell-derived therapies in the future.

For decades (or perhaps centuries) the approach in cell biology has remained relatively unchanged. We isolate cells and with our confined knowledge of their endogenous conditions, begin to experiment until we can sustain them in vitro. Once established, we can conduct further investigation to assess a cells response to different conditions, changes over time or response to manipulation. This is especially true of stem cell biology, established from tireless efforts to incrementally improve culture conditions or differentiation protocols based on fragmented knowledge of developmental processes. Despite this, the promise of stem-cell therapies is already being realised in the clinic, but the breadth of cell types being used is still relatively narrow. Recent technological advances in the field have been focused on the safe and scalable manufacture of therapies. While these are revolutionary breakthroughs, the applications are largely limited to T cells, haematopoietic- and pluripotent-stem cells (HSCs and PSCs), a small fraction in the grand heterogeneity of cell types. Consequently, the lack of cell source diversity prevents cell therapy from fulfilling its clinical potential, pointing to the need for new means to isolate or generate source cells.

Miracle cures and fast-track approval threatens medical advances, say scientists – The University of Manchester

Prof. Volker ter Meulen, Co-chair of the EASAC-FEAM Working Group and Past President of EASAC, said: Stem cell and gene-based therapies hold great medical promises. But we are alarmed over a trend to lower requirements of evidence. Also, we see an increasing problem of commercial clinics offering unregulated products and services

The Academies say the idea of regenerative medicine is to tackle diseases which up to now are incurable. According to the report, cosmetic applications, for example, are inappropriate for the time being.

So far, regenerative medicine has proven itself only in few specific clinical indications, for example for skin disorders. Yet, we see an increasing number of unregulated clinics promising a wide range of benefits on the basis of poorly characterised medicinal products with little evidence of effectiveness. They usually advertise their services via the internet with the primary intention of financial profit, explains EASAC Biosciences Programme Director Dr. Robin Fears.

The scientists urge the EU to resist the pressure and put patients first. When countries lower regulatory standards in their eagerness to support national economic interests, it is even more important for the EU as a major global player to defend the principles of international cooperation in health regulation, says Prof. George Griffin, Co-chair of the Working Group and President of FEAM.

We all want cures to be available in the shortest time frame possible. But our analysis and recommendations aim at ensuring that regulatory procedures are robust, transparent and evidence-based, concludes Cossu. Scientific research and proof are more important than ever. The EU and national regulators should be wary of not undermining public trust in science.

MSC Therapy for Acute Respiratory Distress Syndrome; It’s Time to Accelerate Clinical Trials for COVID-19 Patients in Need – PRNewswire

WASHINGTON, June 3, 2020 /PRNewswire/ --A new systematic review and meta-analysis of clinical studies using mesenchymal stromal cells (MSCs) led by a team at the Mayo Clinic, and including researchers from Emory, Duke, Case-Western, and the University of Miami, shows a trend toward improved outcomes and reduced mortality for patients with acute respiratory distress syndrome (ARDS), a major complication for patients with COVID-19. This studyand several othersalso have shown that MSCs are safe for patients.

Based on these findings, the authors call for the rapid commencement of large-scale, confirmatory clinical trials to build on the existing evidence base, which shows a trend toward improved pulmonary function and reduced severe lung inflammation for patients with ARDS, paving the way toward another treatment option for seriously ill patients with COVID-19.

To date, nearly two million Americans have tested positive for COVID-19 and more than 100,000 Americans have died. In its most severe form, COVID-19 leads to ARDSa life-threatening lung injury that allows fluid to leak into the lungs and makes it difficult for patients to breathe. More than 40 percent of individuals hospitalized for severe and critical COVID-19 develop ARDS, and 22 percent to 62 percent of those who are diagnosed and become critically ill, die from the disease. There is no effective treatment for ARDS today; MSCs potentially offer a unique therapeutic option to help patients in need.

"The analysis shows a positive trend in outcomes when treating ARDS patients with MSC therapy and represents the potential to save thousands of patients with COVID-19 induced ARDS," said Wenchun Qu, MD, PhD of the Mayo Clinic and first author of the paper. "The potential benefitcombined with the demonstrated safety of these therapiessupports the need for rapid commencement of more clinical trials."

"Acute respiratory distress syndrome is a rapidly progressive disease that can occur in critically ill patients," said Anthony Atala, MD, Editor-in-Chief of STEM CELLS Translational Medicine and director of the Wake Forest Institute for Regenerative Medicine. "Having additional potential therapies, such as MSCs, could be highly beneficial to patients with COVID-19."

To date, the FDA has approved more than a dozen investigational new drug applications for the use of MSCs for COVID-19-related conditions. The National Institutes of Health (NIH) has also supported the use of MSCs and other regenerative cell therapies to help patients with other conditions. The bipartisan 21st Century Cures Act provided $30 million in funding to the NIH over three years for clinical research for such therapies. However, these limited investments expire in fiscal year 2020.

The Alliance for Cell Therapy Now and the Regenerative Medicine Foundation support the recommendation of the authors, who urge funding for larger studies that build on the results to date. Collaboration and funding are also needed to collect and analyze the evidence from multiple ongoing and new studies, to better evaluate outcomes and potential benefits of MSC therapy for COVID-19 patients in need. A portion of the more than $10 billion in funding directed by Congress to the Biomedical Advanced Research and Development Authority (BARDA) and the NIH for COVID-19 should be used to support these goals.

Groundbreaking Gene Therapies for Hereditary Diseases / Alessandro Aiuti, a physician and research scientist from Milan, receives the Else Krner…

The current coronavirus pandemic clearly illustrates how dangerous viral infections can become for us. Independent of the present situation, there are people whose bodies are defenseless against infections because their immune systems are unable to combat them - they suffer from immunodeficiency diseases such as ADA-SCID (adenosine deaminase severe combined immunodeficiency) or Wiskott-Aldrich syndrome. Prof. Dr. Alessandro Aiuti, a physician and research scientist based in Milan who works at the San Raffaele-Telethon Institute for Gene Therapy (SR-Tiget) and at the Vita Salute San Raffaele University, is now being honored with the Else Krner Fresenius Prize for Medical Research 2020 for his groundbreaking successes in the development of gene therapies. The award is coupled to 2.5 million euros in prize money.

In the case of the rare immune disorder ADA-SCID, which exclusively afflicts young children and occurs about 15 times a year in Europe, a defective ADA gene within the genome disrupts lymphocyte development, leaving the young patient's body defenseless against infections. "Without effective therapy, the children rarely survive for more than 2 years because any infection can become perilous for them," Aiuti explains. Standard for this therapy is a bone marrow transplantation from a fully matched sibling. However, a suitable donor is available only for a minority of patients. "Meanwhile children with such a condition benefit from the advances we have made in the field of gene therapy. So far we have treated 36 children from 19 countries using the therapy we developed. In more than 80 percent of the cases, the treatment has had such an impact that no enzyme replacement therapy or transplantation is needed. This achievement has been made possible by the extraordinary effort and dedication of SR-Tiget researchers and clinical team throughout 25 years," Aiuti adds. All of the patients are still alive.

For these successes and his other work in the field of gene therapy, Alessandro Aiuti has now been honored with the Else Krner Fresenius Prize for Medical Research 2020 awarded by the Else Krner-Fresenius-Stiftung (EKFS) foundation. At 2.5 million euros, this award is one of the highest endowed prizes for medical research in the world. "Still young by comparison, this year the prize is being awarded for the third time. It honors research scientists for pioneering contributions in the areas of biomedical science. A major percentage of the prize money flows into the prizewinner's research and is supposed to contribute toward achieving further groundbreaking findings and medical breakthroughs in the future as well," emphasizes Prof. Dr. Michael Madeja, scientific director and member of the management board at EKFS.

The decision regarding the prize recipient was made by a ten-member international jury composed of renowned research scientists in the fields of genome editing and gene therapy along with delegates from the Scientific Commission at EKFS. Prof. Dr. Hildegard Bning, chairwoman of the jury and president of the European Society for Gene and Cell Therapy (ESGCT), substantiates the jury's decision: "Alessandro Aiuti is a truly outstanding physician and scientist. His work has decisively contributed to the development and successful treatment of rare, genetically caused disorders such as SCID. Thanks not least of all to the contributions he has made, even patients with other inheritable illnesses can presumably be treated successfully in the future."

After successful clinical trials, the gene therapy developed for ADA-SCID patients was approved as a pharmaceutical remedy in Europe. It is considered to be one of the key findings in the development of gene therapies worldwide. With this treatment certain blood stem cells (CD34+) are taken from the patient, then the cell DNA is modified. The cells are treated outside the body using a viral vector to accomplish this. The correct version of the gene for the ADA enzyme is introduced into the genome of the cells that were collected. The genetically modified cells are returned to the patient's bloodstream via intravenous infusion. A portion of the modified cells subsequently establish themselves in bone marrow again. The patient now has blood stem cells that function properly and produce lymphocytes to defend against infections - presumably on a life-long basis.

Alessandro Aiuti wants to utilize the prize money from EKFS to set the success story forth, to optimize the therapies further and map out the healing mechanisms involved in a better fashion. The scientist sees another major challenge in conveying the acquired knowledge beyond the successful gene therapies from Milan to as many other genetic disorders as possible. Alongside the therapy for ADA-SCID, the San Raffaele Telethon Institute for Gene Therapy has also developed gene therapies for four more hereditary diseases, among them the Wiskott-Aldrich syndrome and metachromatic leukodystrophy (MLD). To this day a total of more than 100 patients from 35 different countries have been treated.
